The Koenigsegg Agera One:1 is a car as fast as its name is difficult to pronounce. Thankfully, you'll have better things - like evading the cops or catching racer punks - to worry about should you choose to give it a spin in Need for Speed: Rivals. The car is now available to download for free, and comes in both racer and police variants.
According to the Need for Speed blog, the real-life Agera, "possibly the fastest car ever built," packs 1340 BHP (or brake horsepower, which is to say horsepower that doesn't factor in an engine's natural loss in power) and weighs 1340 kilograms. That's one BHP per kilogram, a 1:1 ratio! Oh. Ohhhhhhhh. Hold up. Nevermind. We just got it.
